APPARATUS FOR CARBURETING AND ODORIZING NATURAL GAS.

SPECIFICATION forming part of Letters Patent No. 316,033, dated April21, I885.

Application filed January 14, 1885. (No model.)

' To all whom it may concern.-

Be it known that I, SAMUEL J. Harris, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulApparatus for Carbureting and Odorizing Natural Gas; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof.

Heretofore the presence of natural gas unconfined in any room orapartment could not be readily recognized by any of the senses untilignited, there being an absence of asufficiently distinct andperceptible odor, and consequently many accidents, explosions, anddeaths have resulted from the use of this gas, and so far as I am awareI am the first to devise' and invent a process of odorating the naturalgas preparatory to its use.

My process of odorating natural gas consists in evaporating naphtha,benzine, or any other odorizing material by placing the naphtha or othersuitable substance into a pipe or receiver in such a manner as to beproperly and fully exposed to a current or currents of the natural gas,and at the same time or simultaneously causing the gas to pass forciblyupon and over the same as it passes en route to the consumer, and insuch a manner as will best evaporate and odorize the gas. For thispurpose there must be a gradual and continuous supply of the odoratingmaterial. Therefore I have invented the following-described apparatusand appliances to render this process effective and to produce thesedesired results, reference being had to the accompanying drawings, inwhich- Figure 1 represents an elevation in section of my improvedapparatus for odorating natural gas. Fig. 2 is a longitudinal andvertical section of my improved cut-off valve. Fig. 3 is a like sectionshowing my modification of valve. Fig. 4 is a section on the line 22,Fig. 3.

- Fig. 5 represents my screw-cap with handles other material, and isscrewed ontothe vessel or pipe 0, as indicated in Fig. 1.

a is a glass tube inserted in A at a a for the purpose of determiningthe quantity of the odorizing material in the vessel A.

a a are eyelets or clasps onthe vessel A, to receive and support theglass tube'a.

a is the opening at the top of A to receive the odorizing substance.

CF represents a tube through which the gas passes into the vessel A.

O and O are holes or slots through which the odorizing material passeswhen the slide D is withdrawn.

. e e 6 represent sheets, made of cotton or other suitable fabric,secured to the pipe E by means of coiled (and other) wire attachments,and adjusted, as indicated, to receive and disburse the odoratingsubstance. There may be three (more or less) of theseevaporating-sheets.

D represents the horizontal adj usting-pipe; D the screw-cap; D thecrank to the screw D; D, the anchor for the screw, and D the slide partof the valve.

Having thus described my apparatus and appliances, I now desire to showthe working of this new and useful process of odorating the natural gasfor use as fuel and light.

The entire apparatus, as shown in Fig.1, being placed in position withthe horizontal adjusting-pipe D and its accompanying valveslide D, thescrew-cap D is removed, and the slide D is moved in position to coverthe gastube 0 and the slot or slots 0 by the turning of the crank D Thenthe screw-cap B is removed, and the vessel A is filled with naphtha orother odorizing substance, when the cap B is replaced and the slideD isgradually withdrawn, or so regulated as to allow the required amount ofthe odorating substance to drop through the pipe O onto thedepositingsheets 6 e e", while simultaneously the gas is made to passthrough the pipe E, and thus the strength of any given odor may be regu-,lated by the gradation in the supply of the odorating material. Thescrew-cap D is then replaced, and the gas is continuously odorated as itpasses to the consumer.

The modification of this valve as shown in Figs. 3 and 4 opens or closesthe gastube 0" and the slot or slots 0 by the turning of the handleorcrank shown in Fig. 4. When the modification of this valve or a tapand faucet is used, the slide'D, with its attending adj ust- 5 ingdevice D is dispensed with.

The office of the pipes (J is to afford gaseous pressure on the contentsof reservoir A to insure the outflow thereof.

Now, having described my process of odorro ating natural gas and myimproved apparatus for the same, what I desire and claim in LettersPatent'is--- v V 1. The combination of the gas-pipe E and the folds e ofabsorbent material arranged I 5 therein with pipe 0, above saidmaterial,

my hand this 2d day of January, A. D. 1885. 2 5
